NABL vs NADCAP: What’s the Real Difference, and Why Should You Care? If you’ve spent any time sourcing an NDT testing lab in India, you’ve almost certainly seen both acronyms sitting side by side on a vendor’s website — usually right under the logo, in bold letters: “NABL & NADCAP Accredited.” It looks impressive. It’s meant to. But […]

What kind of flaws will Radiography testing detect? Objective of Radiography Testing is to detect internal flaws. Volumetric flaws such as voids, pinholes, slag, shrinkage are easily detected, whereas, planar defects such as laminations, laps and seams are difficult to defect. A defect should create notable amount of sectional difference to get detected. Flaws whose

In Magnetic particle testing, to detect a flaw these should be sufficient flux leakage. Greater the flux leakage at the flaw area better is the detectability. For sufficient flux leakage to happen, there should be adequate current to be present. Therefore, to detect flaw of a certain size, current needs to be properly calculated. Just
